Smooth trends in fermium charge radii and the impact of shell effects

1. Fascinating information on a subject few of us know about but is also fundamental.

In my short life-time I've watched the periodic table expand and get filled in with actual sightings of some of these very rare elements. I actually met Glenn Seaborg in the early 60s in Geneva at the UN. Unfortunately I was too young to understand his stature.

Do you think there may be significant discoveries yet to be made in these heavier transuranic elements? Islands of relative stability from radioactive decay? I think I've read some new research indicating that certain isotopes of some non-naturally occurring elements may have increased stability. And what would be the implications?
